How the fake email checker works

ZeroBounce can detect fake emails through its in-depth email list validation process. Here’s how we verify email authenticity:

  • Syntax checks — Does your email use the correct format or contain typos? If yes, the email address is fake.
  • DNS record/SMTP checks — Even if the format is legit, you need to know if the mailbox is real. We validate email addresses with record checks to ensure that they’re real and configured correctly.
  • Spam trap checks — Our fake email checker also checks for known spam signatures, allowing you to detect and avoid problematic emails.
  • Verify+ from ZeroBounce — While we detect fake emails, we’ll also look for ‘disabled’ email accounts. These are common with Yahoo and AOL domains and will lead to a bounce, just like fake email addresses.
  • Further investigation — If the fake email checker doesn’t detect any problems, we’ll pursue an additional investigation to check for suppression lists, catch-alls, disposable domains, and toxic domains. All of these will hurt your email marketing efforts.
TL;DR — If the fake email checker detects any fake, invalid, or problematic emails, we’ll tell you. And, if we encounter any temporary ‘unknown’ results, we’ll continue to recheck with different tactics until we obtain an accurate result for you.
